Sets of nanostructured PP films have been prepared using various techniques and procedures. They have been subjected to mechanical tests (stress-strain curves and to impact strength tests) and have been subjected to electrical space charge tests by means of Pulse ElectroAcoustic techniques. Suitable analysis about the relevant correlations were performed and did produce results useful from the quality...
The thermo-mechanical and the electrical characterization of some nanocomposites prepared from bisphenolic epoxy resins and different nanoclays are presented. The study of the nanocomposites morphology revealed a good dispersion of the nanoclay in the epoxy polymer. The dynamic modulus was found to be higher for the nanocomposites irrespective of the nature of the adopted clay. The space charge accumulation...
A set of surface discharge ageing procedures, space charge observations and dielectric strength measurements has been implemented on a type of insulating nanofilled epoxy-resin (nanostructured by compatibilised synthetic layered silicates) and on its non-filled base resin. Promising improvements in the electrical behaviour of the nanofilled epoxy, particularly as concerns surface discharge endurance,...
